In a small bowl combine cumin and the next 6 ingredients (through black pepper). Season chicken and grill outdoors or on indoor grill pan for ~8 minutes or until cooked through (can also use a skillet if no grill pan). Once cool, cut into a very small cubed dice.
In a large bowl, mix chicken, diced apple, onion, celery, Greek yogurt and mayonnaise. Stir. Season to taste with a pinch of salt and pepper. Enjoy on a sandwich, with crackers or stuffed in a tomato or avocado.
Notes
Chicken tenders or thinly sliced chicken breasts work best for this recipe so you can get a small dice on the chicken and a good coating of the spice mixture.
